The present invention describes a specialized exercise apparatus and method for use that targets the muscles in and around the abdominal, oblique muscles and mid section of the body. Each of the auxiliary ground electrodes has an inner side surface facing the center electrode through the porcelain insulator to define an auxiliary spark gap between itself and a nose of the porcelain insulator so as to occupy a minimum distance between the porcelain insulator and the auxiliary ground electrode. The present invention relies on a precipitating solvent being added to an aqueous solution comprising the subject compound to form a precipitate of the subject compound, which may be further dried andor purified. The system includes media servers that communicate with the multi-service servers for providing media content to the multi-service servers. An equalizer in the receiver is also used to track timing and channel variations.
